Sincerbeaux assignor to Underwood New York, N. Y., a corp West Hartfcrd, Conn., Elliott Fisher Company, oraticn of Delaware Application December 30, 1939, Serial No. 311,739 5 Cl,ims. (Cl. 235133) This invention relates to adding and calculating machines and more partlcularly to a transfer mechanism for the accumulators or totalizing registers of such machines. V

The principal objects of the invention are to improve the construction and mode of operation of transfer mechanisms for the totalizing registers of machines of the above classes and-t produce a novel and improved transfer mechanism for eiecting the transfer from a lower to a higher dnomination either while the accumulator train of the higher denomination of the register is in the midst of an accumulating operation or while said train is idle except for the transfer operaticn.

With these objects in view, applicant has produced a transfer mechanism which is adapted to be employed in both adding and calculating machines to eiect the above results and which at the same time is simple in construction and reliable in operation and may be produced at a relatively low cost as compared With prior mechanisms of this character.

The invention will be readily understood from the accompanying drawings illustrating the Various features of the invention in their preierred forms and the following detailed description of the constructions therein shown.

The accumulator or register mechanism illustrated in this application is particularly constructed and arranged to be embodied in a multiplying machine such as illustrated and described in the co-pending application of Samuel A. Neidich, Serial No. 311,733, filed December 30, 1939.

The register mechanism comprises a series of trains of accumulator or register wheels having substantially the same construction, arrangement and mode of operation of parts. Each of these trains includes an indicating or value wheel 2 fixed to a sieeve 4 rotatably mounted on a normally stationary shait 6 supported in bearings in side plates 8 secured to the base il) of the machine. Upon the sieeve 4 is fixed a gear wheel i2 meshing with a gear wheel l4 forming one member of a unit rotatably mounted on a driving hub [6 journaled on a fixed shaft I8 also supported at its ends in the side plates 8. Said unit also comprises a toothed ring 2!) and a disk 22 and these three elements are secured together by a series of pins or rivets 24. The unit 15 heid from axial movement in one direction on the driving hub [6 by means of a fiange 26 on said hub [6 and is held irom axial movement in the opposite direction on Said hub by means of a gear Wheel 28 secured to'the hub by means of rivets 29 as shown in Figs. 3 and 5.

The unit is normally driven from the hub by means of a yielding driving paWl 30 (sec Fig. 6) formed on a supporting plate 32 secured to the driving hub by means of screws 34. This pawl is arranged to engage the ratchet teeth 36 formed on the periphery of the ring 2!) to drive the unit and the value wheels.

The driving hub [6 is itself driven by means of a gear wheel 38 meshing with the gear wneei 28. The gear wheel 38 is mounted upon a supporting sieeve or carrier 49 fixed upon a shait l2 mounted in bearings formed on suitable brackets 43 secured to the frame of the machine and the shaft 42 is driven continuously during the multiplication of the multiplicand by the several digits of the multiplier. The gear 38 is arranged to be driven from the sieeve 40 under certain conditions through a suitable frictional driving mechanism.

'Io each of the gears 38 is secured a peripherally toothed disk 44, this disk and the gear rotating as a unit When driven from the sieeve 40. The bear 38 is engaged on one side by a disk or washer 46 of suitable friction material such as rubber, this disk being interposed between the gear and a radially extending fiange 48 formed on the sieeve 40. The toothed disk 44 is engaged upon its outer face by a disk or washer 5 oi suitable friction material mounted on the sleeve 40 and interposed between the toothed disk and a dished spring disk 52 secured to the sieeve. This spring disk is provided With a central opening through which a reduced hub portion 54 of the sleeve passes, the disk resting against a shouldr on the sleeve, and the disk is secured "in place onthe sleeve by means of a nut 55 cumulator train in operation during said cycle,

is rotated until the partial productcorresponding to the particular train is entered in the value wheels and the rotation of the disk M and the gear 33 is then arrested to retain said partial the cycle. he rotation 0: the disk 44 is arrested, when a particular partial product corresponding to the train in Which said disk is located is registered in the value Wl1eels, by means ofa pawl 58-pivcted on a shalt Silex-tending'along tne trains ,of accumulator wle'ls substantiallv parallel with the shaft 42, said pawl being arranged to engage tne peripheral teeth on the disk to arrest the rotation of the disk.

Thispavvl -is engaged W-itn the toothed disk only momentarily by the momentary energization of the magnet M and then is disengaged from the disk; Upon the disengagement of this pawl from the disk, the dsk* is held rom rotation during the remainder of the cycle by a holding pawl 62 pivoted on the shait 6ai at the side of the pawl 53 and arranged to be'en.gaged Witl the disk oy the disk ngaging movement of the pawl 58. Thepawl 58;the magnet 6l,the holding pawl 2, the actuating and locking lever 55 for locking the holding pawl in engagement with the disk 4 3 and for disengaging said pawl frein the disk, the bail 65 for actuating said lever, and 7 the cam 68 for operating the bail ail have the same construction, arrangement and mode of operation 'as the corresponding parts of the mechanism illustrated and described in the Neiclich application, referred to above.

In the present construction there are two sets of value indicating numbers from'natight to nine on the value Wheeis 2, a half rotation of each value wheel registering an addition of ten in each wheel. The ratio of the gear Hi to the geai i2 istwo to one and the ratio of the gear 38 to the gea.r"28 is two an one half to one. Therefore, during eacn complets rotation of the gear 38 and the toothed disk 341 of each train of the accumulators, the corresponding value wheel W111 rotate' through fiVe' revolutions.

The registeris provided with a series of improved trariSfer me chaniSns each ci: which will operaLte to transfer carry values or increments froin the train et accumulator wheels of lower order to which it is applied totne next liiglr order, whether the Wheels of the latter accumulator train are stationary 01' are ir1iotation. Eacn trarisfer mechanism comprises a lever E63 (see Fig. 6) riivoted at 12 to the drivlng hub l6 and carrying a pawl ii pivoted at lis on the lever and acted upon by a coiledspring 18 which main tains the pawl in engagement With the teeth or the ring 20. The lever Hi isactecl upon by a coi lecl spring.8 which maintainsa contact proiection 82 on the lever in engagement With an actuator 8l rotatably, and slidably mountedon 7 1-5 product in said wheels until the completion of 84 is located on the shat 48 in a position remote from the driving hub l6 as illustrated in Fig. 5, the lever i5! thon engaging the inner left hand portion of the conical surface of the actuator as shown in said figure. During a transier operation, the actuator 8 i is rnovecl along the shait iB frorn the position shown in Fig. 5 to the position shown'in Fig. 3. Duringtnis movement of the actuator, through the engagement of the lever le with the conical portion of the actuator, the lever is svvung in a clockwise direction (Fig. 6) thereby turning,the toothed ring 20 one tooth forwardly with relation to the driving huc and advancing the gear H; With relation to the driving gear'26 to enter an additional one in the value wheel 2, the spring pawl 3l! theieafter engaging the ring 26 at a point one tooth to the rear of its former position relation to the direction of rotation et ring 253. This action will occur Wnether the driving hub is rctating or whetner it is 'Staticnaiy.

Themechanism foi moving the actuator 8 irom the position shown' in Fig. 5- to the position shown in Fig. 3 comprises bel] crank le,- ver 85 pivoted on a -stud 63 having its ends*sup ported in projections 9) on a =braeket secured-to the base of the machine, the upwardly extend ing 'arm cf whichlever i5, ferked to embrase the actuator 3 3 and 'carries pins E.-2 sec-ured in the respective arms -of the -fork whi-ch engage in a groove '-l in the actator. The laterallyextending arm of the lever 2is acted npon by a coiled spring 86 which normallmaintains the lever in the position shown in Fig. 5 with the actuator in its right hand position on the shaft i5. The lever i is Swung in a counterclockwis direction Figs. 3 and5 'to shi-t theactuatcr froni the position shown in Fig. 5 to that shown in Fig.f3 loy means o-f a lever 93 -whieh i-s pivoted upon the end portion of one of the studs -8& andls A provided with a laterally extendilgcontact pro jection I' arranged' tube engaged by a cam projection l2 formed on the corresponding disl: 22. Each of the levers 98 extendg laterally*of the machine from its pivotal point benth the disk 22 of the train of accumulatcr wheels corresponding to one order of the register meehanism and through an opening or slCt ififi" (sec Fig. 4) in the upwardly exte1idihg arm cf the bell crank lever SES-cf the transfer m chanism of the acoumulator train of the next higlier-order and is formed With a downwardly projeeting and portion 35 arranged to engage the latrally extending'arm of said bell crank.

When a value Wheel-2 of one of the trains of accumulators is moving from the nineposition to the n-tught position, the cam i 32 onthe disk 22 of said train engages the projection i3* on vance movement of the gear Mtlievalue wneel the lever 98 and depresses said lever. The de pression of said lever moves the aetuator ,8ii of the train of the next higher order to the left (Figs. 3 and 5) ficm the position shown inFig. 5 to that shovvn in Fig. 3 thereby actuatihg the lever and the pawl i i te advahce thegar 14 with relation to thegar 28. By adof the train of said higher o'rder isadvanced a distance sufiicient to enter an additional one in said Value wheel. Since thegear Hi and the disk 22 for each train of the a-ecurfi'ulators rfiake a quarter ofa revolution for the rotation of-each value wheel an 'angulardistarice corresponding to-ten number spaces, there are four of the cam projection i92 formed on each* disk 22 toactuate the transfer- -mechanisrh once for each quarter of a revoiution of the disk 22 and the ear 14.

When the cam projection 102 on a disk 22 disengages the contact projection 180 on the corresponding lever 98, said lever and the bell crank 85 are restored to initial position by the action of the spring 96, the actuator 84 is moved back to the position shown in Fig. and the lever 78 is swung back on its pivot in a counter- Clockwise direction (Fig. 6) with relation to the driving hub [6 and the pawl 14 is retracted with relation to the toothed ring 20 into position to engage a tooth on said ring one tooth back of its former position.

In the construction shown, the train et accumulator wheels at the extreme right in Fig. 3 is the units train, the next train to the left the tens train and So on. These trains correspond to the train adjacent the bottom of the sheet, the next higher train and so on, in Fig. 1. There is, of course, no actuator 86, lever 10 or pawl 14 for the units train and no lever 38 for the hundred thousands train which is incomplete, this train having ne gear 38 or toothed wheel 44. The toothed ring 28 of the units train might be fixed to the driving hub since there is no relative movement between these parts as is required in the other trains for the transfer operation. In order to employ uniform parts in the several trains, however, ring 20 of the units train is driven from the driving hub by means of a spring pawl 38 secured to said hub.
